Hello ,
I am playing with PDK NRF 5340, I am trying to write a simple code to configure a PIN (0.10) which is not already in use by PDK.
When I print it's state it always says "LOW". here is my code.
#include <zephyr.h>
#include <sys/printk.h>
#include <device.h>
#include <drivers/gpio.h>
unsigned int status=1,old=1;
void main(void)
{
struct device* port0 = device_get_binding("GPIO_0");
int result=1;
result = gpio_pin_configure(port0, 10, GPIO_DIR_IN);
printk("Hello World! %s, %x \r\n", CONFIG_BOARD,result);
while (1)
{
gpio_pin_read(port0,10,&status);
if(old != status)
{
if(status==1) { printk("HIGH"); }
if(status==0) { printk("LOW"); }
old = status;
}
}
}
what my serial output says is -

and that's it It stays LOW no matter how I connect Pin 0.10 to GND or to 3.3v (vcc) from PDK itself.
I am using SES (nordic edition) v4.52
OS windows 7 64 bit
NCS_TAG is v1.2.0
Thanks and Regards
